ORLANDO, Fla. -

The brother of George Zimmerman, the neighborhood watchman who shot and killed 17-year-old Trayvon Martin, says President Barack Obama bullied his family in the Martin case, according to a report.

According to Breitbart News, George Zimmerman's brother, Robert Zimmerman Jr., said his family felt "bullied" by President Obama when Obama commented on the case at the White House, saying that if he had a son, he'd look like Trayvon Martin.

"I think we felt bullied, we were a little let down initially, and that disappointment grew because if you don’t have the support of at least the law on your side, of the most powerful man in the Western Hemisphere ... bringing up statements about his skin color … it was alarming to say the least," Robert Zimmerman told Breitbart News in an interview.

Robert Zimmerman also told Breitbart News that he didn't think a "white president" would have been able to make such comments.

George Zimmerman has pleaded not guilty to second-degree murder, claiming he acted in self-defense. The delay of his arrest in the Feb. 26, 2012 shooting death sparked national outcry.
